# Rigetti Computing

> Rigetti Computing is a full-stack quantum computing company building superconducting quantum processors and delivering access through Quantum Cloud Services (QCS). Developers program Rigetti QPUs in the Quil instruction language via the open-source pyQuil SDK, compile with quilc, and simulate locally with the Quantum Virtual Machine (QVM). The QCS HTTP API exposes REST-style operations for quantum processors, instruction set architectures, engagements, endpoints, reservations, groups, billing, and account management, secured with OAuth2 (Okta) JWT bearer tokens.
